analysisLayer

(Required)

The point feature layer for which clusters will be found.

Syntax: As described in detail in the Feature input topic, this parameter can be one of the following:

• A URL to a feature service layer with an optional filter to select specific features
• A feature collection

Examples:

• {"url": <feature service layer url>, "filter": <where clause>}
• {"layerDefinition": {}, "featureSet": {}, "filter": <where clause>}

minFeaturesCluster

(Required)

A double value that will be used as the minimum number of features to be considered a cluster. Any cluster with fewer features than the number provided will be considered noise.

Example: "minFeaturesCluster": 5

method

Specifies the method that will be used to find clusters. If the method is not specified and the searchDistance value is not provided, the HDBSCAN algorithm will be used. If the method is not specified and the searchDistance value is provided, the DBSCAN algorithm will be used.

This parameter is available in ArcGIS Enterprise 11.2 or higher.

Values: DBSCAN | HDBSCAN | OPTICS

Example: "method":"OPTICS"

searchDistance

A double value that will be used as the maximum distance to search for neighboring features.

The units of the search distance value is supplied by the searchDistanceUnit parameter.

Example: "searchDistance": 154

searchDistanceUnit

The linear unit that will be used with the distance value specified for searchDistance. You must provide a value if searchDistance has been set. The default is Miles.

Values: Feet | Miles | Meters | Kilometers

Example: "Units": "Kilometers"

sensitivity

A double value between 0 and 100 that determines the compactness of the clusters.

This parameter is available in ArcGIS Enterprise 11.2 or higher.

Example: "sensitivity": 22

outputName

The name of the output.

If provided, the task will create a feature service of the results. You define the name of the service. If an outputName value is not provided, the task will return a feature collection.

{
  "serviceProperties": {
    "name": "<service name>"
  }
}

{

  "itemProperties": {
			"itemId": "<itemID of the existing feature service>",
			"overwrite": True
	}
}

{
"serviceProperties": {
    "name": "<existing service name>"
  },
"itemProperties": {
				"itemId": "<itemID of the existing feature service>",
				"overwrite": True
	}
}

context

The Context parameter contains the following additional settings that affect task operation:

• Extent (extent)—A bounding box that defines the analysis area. Only input features that intersect the bounding box will be analyzed.
• Output spatial reference (outSR)—The output features will be projected into the output spatial reference.

{
"extent" : {extent},
"outSR" : {spatial reference}
}

f

The response format. The default response format is html.

Values: html | json | kmz

pointClustersResultLayer

The result of FindPointClusters is a layer containing clustered points.

Example:

{"url": 
"http://analysis.arcgis.com/arcgis/rest/services/tasks/gpserver/findpointclusters/jobs/<jobId>/results/pointClustersResultLayer

The result has properties for parameter name, data type, and value. The contents of value depend on the OutputName value provided in the initial request.

• If the OutputName value was provided, value contains the URL to the feature service layer.
  {
  "paramName":"pointClustersResultLayer", 
  "dataType":"GPString",
  "value":{"url":"<arcgis featureservice layer url>"}
  }

  {
  "paramName":"watershedLayer", 
  "dataType":"GPString",
  "value":{"url":"<hosted featureservice layer url>"}
  }

• If no OutputName value was provided, value contains a feature collection.
  {
  "paramName":"pointClustersResultLayer",
  "dataType":"GPString",
  "value":{"featureCollection": ... }
  }

See Feature Output for more information about how the result layer or collection is accessed.
